The church stands behind a churchyard wall along the roadside in the small village of Hemmesdynge, its harmonious form completed by a tower to the west. It was built on a Romanesque plan with a nave and a slightly narrower chancel ending in an apse, oriented east–west. Much of the original masonry survives, laid in monk bond brick with a rich lime mortar; investigations have found traces of early lime-wash and painted decoration imitating stone quoins beneath later plaster.
The chancel's vaults are thought to date from the church's earliest period, with further vaults added over the nave, probably in the 1400s, and a third vault and the tower added when the church was extended in the 1850s. That the historic chancel survived at all is credited to the cathedral architect C. G. Brunius, who argued strongly against altering what he considered one of the finest and most remarkable old churches in the district, and urged the parish to recognise its rarity.
The mid-19th-century rebuilding was thorough: the west gable was demolished, old entrance doorways were blocked, larger new windows were fitted, and the interior was replastered, a process that destroyed medieval wall paintings that had probably survived until then. Later work included a full internal redecoration around 1901 in a neo-Gothic style, and a further renovation in 1959–60 under architect Eiler Graebe that largely restored the decorative scheme of the earlier scheme while renewing floors.
The sandstone font is contemporary with the church's oldest fabric; a brass basin, added in the 17th century once infant baptism no longer involved full immersion, sits on top of it. The altarpiece, depicting Christ praying at Gethsemane, was painted in 1862 and has attracted criticism for its awkward execution. A small painted image of Mary, probably made in Italy in the early 1800s, has a striking and uncertain history: it is said to have belonged to a Dutch church, passed through German hands during the Second World War, and later turned up at an antiques dealer in Malmö, from where an anonymous donor presented it to the parish.
In the churchyard, a notable gravestone records the death of a woman named Mätta Larsdotter, who reportedly died while pregnant and, seven days after her death, was said to have given birth to a stillborn son — a story remembered locally as a double sorrow for her husband and father. When farms were reorganised under enclosure, the rectory was moved out of the village; the incumbent at the time, Johan Hindbeck, is said to have laid out an unusual park modelled on the ground plan of Lund Cathedral, said to have been planted with one new tree for each day of the year. The park is now privately owned, and one of the former rectory outbuildings houses a local history museum.
